P54198-B21 HPE ProLiant DL385 Gen11 DDR5 24-Slots CTO Server

Core Architectural Innovations

The DL385 Gen11's power stems from its deeply integrated architecture, where every component is optimized for the next generation of AMD EPYC processors. This synergy unlocks unprecedented levels of performance per watt, security, and management simplicity.

AMD EPYC 9004 Series Processor Foundation

At the heart of the platform lies support for the AMD EPYC 9004 series CPUs, codenamed "Genoa." These processors are built on a cutting-edge Zen 4 core architecture and manufactured with an advanced process node.

Key Processor-Driven Advantages

Core Density and Thread Count

With support for CPUs offering up to 96 cores and 192 threads per socket, the DL385 Gen11 can host an immense number of virtual machines, containers, or application threads in a single 2U enclosure, dramatically consolidating infrastructure.

PCIe Gen5 Infrastructure

Every lane of I/O is doubled in bandwidth compared to PCIe Gen4. This massive I/O uplift is critical for accelerating data transfer to NVMe storage, GPUs for AI workloads, and high-speed network adapters like 200Gb+ Ethernet or InfiniBand, eliminating bottlenecks.

AMD Memory Extension (AMD MEX) Technology

A revolutionary feature that allows the processor to support higher memory capacities per channel, directly enabling the platform's massive 24-DIMM slot design and maximum memory configurations.

Revolutionary Memory Subsystem: 24 Slots of DDR5

The memory configuration is a defining characteristic of this server category. Moving from DDR4 to DDR5 is a generational leap, and the DL385 Gen11 maximizes its potential.

DDR5 Memory Benefits

DDR5 memory operates at significantly higher data rates (starting at 4800 MT/s), providing a substantial boost in raw memory bandwidth essential for data-intensive applications. It also features improved power management with on-DIMM voltage regulation.

Capacity and Configuration Scalability

The 24-slots, operating in a 12-channel-per-processor configuration, offer extraordinary flexibility. Organizations can start with smaller, more affordable DIMMs and scale to massive capacities—supporting up to 6TB using 256GB DDR5 DIMMs. This allows for cost-effective right-sizing while ensuring a clear, solder-free path for future expansion.

Optimized Storage Flexibility: 8-Bay Hot-Swap 2.5" Design

The 8-bay 2.5-inch hot-swappable drive backplane is engineered for performance and resilience. This configuration is ideally suited for leveraging the speed of modern NVMe Solid State Drives (SSDs) while maintaining options for SAS or SATA drives.

Hot-Swap Capability for Continuous Uptime

The hot-swap design is a non-negotiable feature for enterprise environments. It allows administrators to remove and replace failed or upgraded drives without powering down the server, ensuring 24/7/365 availability for critical services.

NVMe-Optimized Architecture

The backplane and internal routing are designed to support up to 8 NVMe SSDs simultaneously at full speed. When populated with NVMe drives, the storage array can deliver millions of I/O operations per second (IOPS) and extremely low latency, transforming applications like real-time analytics, high-frequency trading, and large-scale virtualization.

Mixed Media Support

While optimized for NVMe, the bays also support SAS and SATA SSDs or HDDs. This allows for creating tiered storage pools within the same server or dedicating specific bays to high-capacity, cost-effective storage for archival data.

Expansion Beyond the Internal Bays

For workloads requiring even more storage, the DL385 Gen11's PCIe Gen5 slots can be used to add HPE or third-party storage controllers, NVMe JBODs, or tape backplanes, providing virtually limitless expansion potential.

Silicon-Rooted Security and Intelligent Management

HPE has embedded security and manageability directly into the server's DNA with the Gen11 series, moving beyond software-based add-ons to hardware-enforced, silicon-level protection.

HPE Integrated Silicon Root of Trust

This is a cornerstone security feature. A unique cryptographic key is fused into a dedicated silicon chip during manufacturing. This key creates a immutable hardware root of trust that validates the firmware (BIOS, BMC, drive firmware) every time the server boots. It detects unauthorized changes or malware in the firmware and can prevent the server from starting, providing a critical defense against sophisticated persistent threats.

HPE iLO 6 Advanced Management

The integrated Lights-Out 6 (iLO 6) management processor is the brain of the server's operational intelligence. It provides secure, remote administration regardless of the server's power state.

Key Features of iLO 6

Cloud-Based Management with HPE GreenLake

iLO 6 seamlessly integrates with the HPE GreenLake platform, enabling IT teams to monitor, provision, update, and optimize their server fleet from a centralized cloud console, streamlining hybrid cloud operations.

Silicon-Driven Security Enforcer

iLO 6 works in concert with the Silicon Root of Trust to enforce security policies, manage secure boot, and provide detailed security audit logs.

Primary Use Cases and Applications

The combination of high core counts, massive DDR5 memory bandwidth, and ultra-fast PCIe Gen5 NVMe storage makes the DL385 Gen11 CTO server a versatile solution for numerous demanding IT initiatives.

High-Density Virtualization and Private Cloud

With potential for up to 192 CPU cores and 6TB of RAM in a single 2U server, this platform is a virtualization powerhouse. It is ideal for consolidating large VMware vSphere, Microsoft Hyper-V, or Linux KVM environments, running hundreds of VMs with consistent performance. Its high I/O bandwidth ensures that "noisy neighbor" effects are minimized in dense virtual deployments.

Artificial Intelligence and Machine Learning Inference

While training often requires specialized accelerators, AI inference workloads can be efficiently run on high-core-count CPUs with ample memory. The DL385 Gen11, especially when equipped with PCIe Gen5 GPUs or FPGAs in its expansion slots, serves as an excellent inference engine for deploying models in production for fraud detection, recommendation engines, and image recognition.

Software-Defined Storage and Hyperconverged Infrastructure (HCI)

The 8-bay NVMe-optimized storage layout, coupled with expansive PCIe Gen5 connectivity, makes this server an ideal building block for software-defined storage solutions like VMware vSAN or hyperconverged platforms. It delivers the low latency and high throughput necessary for HCI nodes to perform efficiently.

Technical Compute and High-Performance Computing (HPC)

In clustered environments, the server's high memory bandwidth, low-latency NVMe storage, and support for high-speed interconnects (via its PCIe slots) make it suitable for technical computing workloads in fields like computational fluid dynamics, financial modeling, and genomic sequencing.
